EXTENSION-LEAF CONSTRUGTXON FOR PERMANENT-T01? TABLES. i'

Application filed August 7, ma serial no; lair/71.

This invention relates more specifically to a construction for pivotally attaching extension leaves to stationary table'tops.

A main object of the invention is the provision of simple table structure of the stationary table top type, in which the foldable extension leaves 'are pivotally attached to the under surface of the table top in order that the leaves when folded beneath the top lo will be effectually` concealed from view, without the necessity of. employing special concealing means. i c

Another object is to provide a leaf pivoting means that when applied thereto will prevent curling or warping of the leaves, and which will operate as a bottom guide to maintain the leaves in alinement vwith the stationary table top.

A still further object is to provide a hinge '.o construction for table extension leaves that will avoid the necessity of employing special forms of metal hinges nov/"generally employed in similarconstruct-ions. The above and other objects are accomplished by the construction described in the `following specification, when taken in conh nestion with the accompanying drawings which form a part thereof, in which: Fig. 1 is a side elevation of a table.

the companion leaf extended.

Fig. 43 is an enlarged transverse section through the table, taken on line 3-3 of :s F f Fig. fl is a full sized detail section through one side edge of the table top, showing the leaf in a folded position. F 5 is a detail section taken on line 5- Fig. 6 is a view similar to Fig. 4 showing the' leaf in an extended position, taken on line 6 6 of Fig. 5.

The table illustrated is of the type known as a davenport or library,7 the leaves pivotally attached thereto when swung yinto an extended position'forining atc dining type. In the drawings 5 designates a pair of supporting legs connected 'together at their bases by a horizontally disposed brace bar 6, the table top 7 of the stationary type being secured to the upper end of the legs. The stationary top is here shown of elongated form, the sides edges 8, 9, lying parallel to each other, while the ends are of seg- Fig. 2 is a bottom plan view of the table ecp showing one of the leaves folded andr mental form, the upper surface ofthetop consisting of a layer of wood veneer custom# ary in tables of this type. Securedfto the under surface of the top 7 adjacent its edges is la depending apron' 10, the outer face being of ornamental configuration.

`'llhe eXtensionleaves 3, el, are pivotally secured to the under-face of the table top at its parallel side edges, and as the leaves vare attached and operate in exactly the same manner only one leafand its pivoting mechanism will be described. j' i i, t p .Secured to the under surface of the extension leaf adjacenty each of its 4segmental ends 11, 12, are wood cleats 13,14, rigidly secured thereto in any suitable manner. `The inner ends 15 of the cleats project a short distance vbeyond the inner edge 16' of the leaf vand are ornamently carved to match the carvings of the outer-face of the depending kapron when the leaf is folded underneath of the top.` The ends 15 of the cleats extend through.openingsv 17 formedin the depending apron and are pivotally secured to a pair of blocks 18 secured to either si'def of the openings 17 by means of pivot pins 20, disposed transversely through the cleats, their ends being mounted in me'tal-bearingsrQl, 22, secured to the under-face of the blocks 18 see Figs. 5 and 6, of the drawings. The under-'face of the table top directly above the cleats and adjacent the. leaf meeting edge of the top is cut-away to form recesses 23 segmental in form, designed to permit the free` movement of the ends l15 of the cleats when the leaf isswung to its extended posit tion, see Fig. 6. The inner edges 15 of the cleatsv are of the same thickness as the width of the table apron, and the thickness of the rear portions to which the leaf 3 is secured is cut-away the thicknessof. the leaf in order that when the same is brought -to an ex-k tended position the top surface of the leaf will lie flush with the table top'surfaceas` shown in Fig. '6, the bottom p'ortionof the projecting ends 15 of the cleats being chambered inthe cut-away or recessed portions 23 of the table.

By mounting the pivot pins 20 of the leaf l exact-ly midway between the segmental sur faces of the recesses 23 and t-he bottom edge of the table apron 10 when the leaf is lfolded beneath the top, it will be apparent that only a small portion of thetop surface of the extension leaf will 'lie below the lower edges of the table apron, and moreover the exposed portion of the leaf will be practically invisible to any observer, as clearly shown in Figs. 3 and 4.

The leaf 3 is supported in its extended position by the usual slide 25 mounted in grooved guide Ways 26 secured to the under face of the liable top, the outer end of the slide being carved similar to the outer face of the table apron which is cut-away to permit the slide to be pulled outwardly into operative osition.

lVhen tie leaf is swung underneath the table top the outer edge of the leaf will engage spring metal catches 27 and be supported thereby, a slight inward pressure of the catches being suflicient to disengage the same from the leaf when it is desired to bring the leaf to an extended position.

From the foregoing itwill be apparent that the novel feature of the invention herein disclosed resides in the pivotal attachment of the extension leaves to the table proper, the segmental recesses in the under-faee of the tatble top permitting the leaf meeting edge to swing into engagement with the table top edge when extending the same, and to lie when folded substantially concealed from view by the lowermost edge of the table apron.

What I claim is:

l. An extension table embodying a sta tionary table top, a depending apron around the edge of the table top, a leaf movable with relation to the table top and having an edge adapted to register with the table top edge, a pivoting means for the leaf embodying a pair of cleats secured to the underface of the leaf, the inner ends of said cleats projecting beyond the meeting edge of the leaf, pivot pins secured to each cleat and mounted in bearings secured to the under-face of the table top, the apron at the point of cleat attachment being cut away to permit the ends of the cleats to turn on their pivots, the under-face of the table top being cut away to form recesses directly above 'the inner ends of the cleats, whereby to permit the ends of the cleats to rotate the leaf to a position beneath the table top and above the lower edge of the table apron, the inner ends of the cleats filling the cut-away portions of the aprons when the leafis swung to a chambered position beneath the table top, means to support the leaf in its folded position, and means to support the leaf in its extended position.

2. An extension table embodying a stationary table top, a depending apron around the edge of the table top, a leaf movable with relation to the table top and having an edge adapted to register with the table top edge, a pivoting means for the leaf embodying a pair of cleats rigidly secured to the under-face of the leaf, the inner ends of the cleats projecting beyond the table top meeting edge of the leaf, said ends projecting through openings formed in the table top apron, the ends of the cleats when 'the leaf is folded beneath the table top filling the openings in the aprons, means to pivotally connect the projecting ends of the cleats to the table top, whereby the leaf will be disposed substantially above the lower edge of the table apron when folded, and means to support the leaf in its extended and folded positions. Y

3. In a table, a top having an apron thereon provided with a slot, an extension leaf for said top, a block fixed to said leaf and extending through said slot when said leaf is in position for use, and means for hinging said block in operative position with respect to said apron whereby said leaf may be swung under said top and the butt end of said block rotated to a position tc lill said slot.

4.. A table having a top, a substantially vertical rim extending downwardly from the lower face of said top, said rim having a vertical slot the entire depth thereof, pivot means disposed in back of said rim substantially half-way between the upper and lower edges thereof7 a leaf, and a hinge-block for supportino1 said leaf, said hinge-block being carried by said pivot means, and being swingable from a position in which it extends through said slot and holds said leaf in the plane of said top into a position in w nich said leaf is supported inside said rim and below said top, the butt end of said hinge block filling said slot when the leaf is in folded position.

5. In a table, a top having an apron thereon provided with a slot, an extension leaf for said top, a hinge fixed to said leaf and extending through said slot when said leaf is in position for use, and means for securing said hinge in operative position with respect to said apron whereby said leaf may be swung under said top and the butt end of said hinge rotated to a position to enter the slot.

In witness that I claim the foregoing I have hereunto subscribed my name this 29th day of July, 1926.
